Stop blocking read from a socket but still preserve it
Hello, I have a thread waiting for a socket input...in case I wanted to stop it I need a way to stop blocking receive, but not something like close() or shutdownInput() because I don't want to close the socket but simply shut down the thread...any ideas?
It sounds like you need to set a socket read timeout: see Socket.setSoTimeout(), but exiting the thread and leaving the socket to another thread doesn't sound right. Normally the thread is dedicated to looking after that socket.

my adobe reader does not read my pdf filI think it was screwed up by the other "PDF-READER". I deleted the other "PDF-READER" from my pc, but it still does not work.
Hi wellsfar,
Which version of Adobe Reader you are using?
Is it showing any error message?
A screenshot of the error would be more helpful.

My daughter has an iPod touch using my apple ID, I just purchased an iPhone with the same ID. Is there a way to keep my stuff seperate from her ipod but still share the iTunes account? I was looking through the photo section on my iPhone and found pics my daughter has taken from her iPod. I do not want my pics, emails, etc to show up on her iPod. Is there a way to stop this from happening or do I have to create a different Apple ID for her to use instead?
If you have iOS 8 on all devices then:
If under 13 years create a new ID for her by:
Family Sharing and Apple IDs for kids - Apple Support
The use family sharing to share apps
http://www.apple.com/ios/ios8/family-sharing/
Family purchases and payments - Apple Support
If underage and not i)S on all devices then you have to create an ID for here under your name and supervise it use:
Create a NEW account using these instructions so yo do not have to use a credit card.
Make sure you follow the instructions. Many do not and if you do not you will not get the None option. You must use an email address that you have not used with Apple before. Make sure you specify a birthdate that results in being at least 13 years old
Creating an iTunes Store, App Store, iBookstore, and Mac App Store account without a credit card
More details of how:
http://ipadhelp.com/ipad-help-tips-tricks/how-to-get-free-apps-from-the-app-stor e-without-a-credit-card/
Use the new ID on her iPod but only for:
Settings>Messages>Send and Receive
Settings>FaceTime
Settings>GameCenter
and Settings>iCloud if you want her to have separate Contacts Calendar and some other things.
Continue to use the same/common Apple ID for Settings>iTunes and App stores so you can share purchases. -
How do I stop Adobe Reader from crashing on my unprivileged user?
I am running Windows 7 and I needed to create an unprivileged user on my computer. When I open a PDF file, it almost instantly crashes (I can view the document for about three seconds). If I simply open Adobe Reader without a PDF and click Edit -> Preferences, it crashes. If I open a PDF in any browser, it crashes.
From what I have been able to surmise, it seems that Adobe Reader is trying to read the registry of my privileged user. I have tried uninstalling Adobe Reader, temporarily giving privileges to my unprivileged user, installing Adobe Reader on that user, and then remove the permissions, but the crash still occurs. The only way to stop Adobe Reader from crashing is to start the program as an administrator or change the account type to administrator. How do I stop Adobe Reader from crashing on my unprivileged user?It said "Adobe Reader has stopped working" soon after I opened it, but I was still able to scroll down the document. It was only once I pressed Close Program that it stopped working.
Upon trying it a second time, it immediately stopped letting me scroll down when the program crashed. Here is the error log, I receive the exact same exception code every time:

I have a large library on icloud- 26203 songs is the count when I'm playing over my apple TV, but my itunes only shows 25989 songs. There are songs on icloud that no longer are in my itunes library, or show up in itunes as being on icloud. I want to delete these songs but can't figure out how. I have reset my itunes match on both my computer and my apple tv to no avail.
No. It's on and I update it daily.
When I talk about removing songs from my shuffle play, I'm referring to listening over apple TV. My cloud limit is nearly maxed out, so I am constantly removing/adding songs. That's why I was surprised when I went to delete a song I no longer wanted in the mix and was surprised to find it already deleted from my itunes, but still present in the cloud. I've signed in and out of itunes/and match on apple tv as well, but that didn't remove the tunes in question! -

Trying to read from a socket character by character
Hi all,
I have a problem with reading from a socket character by character. In the code shown below I try and read each character, and then write it to a file. The information sent to a socket sent from a file, and EOF is marked with character of ascii code 28 (file separator). However using BufferedReader.read() I get -1 forever. Is it reading only the last character to have been sent to the socket?
As a side note, if I use readLine() (making sure the socket is sent a newline at end of msg) I can get the message fine. However, I want to be able to receive a message with 0 or many newlines in it (basically contents of a text file), so I want to avoid the readLine() method.
Any help at all is appreciated,
Colm
CODE SNIPPET:
try
serverSocket = new ServerSocket(listenToPort);
System.out.println("Server waiting for client on port " + serverSocket.getLocalPort());
while(true)
inSocket = serverSocket.accept();
System.out.println("New connection accepted " + inSocket.getInetAddress() + ":" + inSocket.getPort());
input = new BufferedReader(new InputStreamReader(inSocket.getInputStream()));
fileOutput = new BufferedWriter(new FileWriter(outputFilename));
System.out.println("Ready to write to file: " + outputFilename);
//receive each character and output it to file until file separator arrives
while(!eof)
inCharBuf = input.read();
System.out.print(inCharBuf);
//check for file separator (ASCII code 28)
if (inCharBuf == 28) eof = true;
//inChar = (char) inCharBuf;
fileOutput.write(inCharBuf);
System.out.println("Finished writing to file: " + outputFilename);
inSocket.close();
catch (IOException e)
System.out.println("IO Error with serverSocket: " + e);
System.exit(-1);
}(tabbing removed as it was messing up formatting)My guess is that the code that is writing to the
socket did not flush it. You said in one case you
could read it (via readln) if the writer was writing
lines (writeln flushes, I believe). Are you writing
the exact same data to the socket in both tests?woo hoo, I hadn't flushed the buffers alright!
for anyone with similar problems, I was missing this from my write-to-socket method:
output.flush();
where output was the BufferedWriter I had created to write to the socket.
Thanks a lot for pointing it out!

How can I change the default pdf reader from the installed (but not yet registered) Adobe Acrobat 9 Pro to Adobe Reader XI? I'm having some hiccups getting Adobe to register the software, but since I set it as the default .pdf reader during setup, things try (and fail) to open in the as yet unregistered software. How can I change it temporariiy to the Acrobat Reader XI that I have installed?
Anubha,
It worked! Thank you so much.
I'd opened file with the 'Open with' feature then clicking Adobe Reader,
but that didn't do it. When I used 'Open with', then 'Choose default
program...', it worked like a charm.
Again, thank you!

What is the easiest way to restore my ipod back to factory specs. It has a red circle with a red x in the middle,please help me to fix my ipod, until now i can't use my ipod..i tried all the procedures in Restore ipod from disk mode but still not working, please help me...
If you are unable to get the iPod into Disk Mode to try and restore it, it's a very good indication, as mentioned in the article, that the iPod's hard drive is damaged and in need of replacement either by Apple or a third party repair company.

4th Generation ipod. Used to charge fine from wall socket (cord and USB adapter) and could also charge on the computer. Suddenly stopped charging from the wall. The same cord and adapter still work for my iphone, so there is not problem with either of them. What has changed? Why won't the ipod charge from the wall anymore? Is there anything I can do about it?
Thanks! It didn't actually work with the one I was using to charge the computer either. We had tried the computer cable with the power adapter, and it didn't work to charge the ipod, though it does charge my iphone. Following your idea further, I waited for my husband to get home from a trip and tried one of his extra cables he keeps in his backpack. That cable worked in with the USB power adaptor. I had thought that because the cable I use on my computer charges my iphone through the USB power adapter or the computer, and that it charged the ipod through the computer that it was fully functional. Apparantly not. Thanks again.

Sockets: How do I know how much I can read from a socket?
Hi everyone,
I've opened a socket connection to a cisco router and want to read some of its databases. These are the main part of my code:
Socket so = new Socket(routerIP, routerPort);
BufferedReader br = new BufferedReader(
new InputStreamReader(so.getInputStream()));
BufferedWriter bw = new BufferedWriter(
new OutputStreamWriter(so.getOutputStream()));
// user/password entered.
bw.write("show ip alias\r\n");
bw.flush();
while ((in = br.readLine()) != null) {
System.out.println(in);
so.close();
The problem occurs in the "while" loop at the end of the code. The last line that the router is sending doesn't have a \r\n at the end and therefore my readLine command waits indefinitly.
Well, I guess I can change that command with a simple read but still it won't be general. I'm looking for a command like "available" in socketImpl that tells me the number of bytes that I can read from the server beforehand.
Any solutions?????????????
Thanks,
Ali.Ok, that much I know from the router. It supports
telnet. So, basically if a telnet client can tell when
it has read all the data coming from the router and
when it has to wait for user to input the data, I have
to be able to do so too.Hi, telnet does not know that it has read all the data coming from the router or from you; It waits for data from both sources (the router and you), and then retransmits that data to (you or the router respectively.)
telnet must be sending and receiving data byte by byte
cause what we type is displayed on the screen if the
server echos the characters back to the client.
Any suggestions, anyone knows of a simple telnet
source?True. In particular, telnet does not care whether there is any carriage return or linefeed characters. It just retransmits whatever it gets from the source to the destination, except that it looks for particular escape sequences from the data source, such as the sequence for shutting out echo when you enter passwords.
In your case, I am not sure what you want to achieve. I think you are trying to find the end-of-data but the end-of-data is not unambiguously terminated by an end-of-line. Maybe you need to find some other character or even strings for that purpose. You may even need to process the whole data received in order to determine the end of it.
However, if you just want just that answer from the router and no more, you can send your logout after your query, so that after the router replies your queries, it also closes the connection and your BufferedReader.readLine() will return.
Maybe you are looking for
